Reconstruction of Postinfarcted Cardiac Functions Through Injection of Tanshinone IIA@ Reactive Oxygen Species-Sensitive Microspheres Encapsulated in a Thermoreversible Hydrogel

引用

Energy & Environmental Materials 2024年第2期7卷 191-203页

作者： Ling Yu Yubin Liang Lei Gao Peipei Chen Zhiqiang Yu Minzhou Zhang Aleksander Hinek Shuai Mao Second clinical College Guangzhou University of Chinese Medicine department of Critical Care Medicine Guangdong Provincial Hospital of Chinese Medicine Guangdong Provincial Branch of National clinical Research Centre for Chinese Medicine Cardiology department of Radiation Medicine and Applied Sciences University of California San Diego department of Laboratory Medicine Dongguan Institute of Clinical Cancer Research Affiliated Dongguan Hospital Southern Medical University Translational Medicine Hospital for Sick Children

Myocardial damage resulting from acute myocardial infarction often leads to progressive heart failure and sudden death, highlighting the urgent clinical need for effective therapies. Recently, tanshinone IIA has been identified as a promising therapeutic agent for myocardial infarction. However, efficient delivery remains a major issue that limits clinical translation. To address this problem, an injectable thermosensitive poly(lactic acid-co-glycolic acid)-block-poly(ethylene glycol)-block-poly(lactic acid-co-glycolic acid) gel(PLGA-PEG-PLGA) system encapsulating tanshinone IIA-loaded reactive oxygen species-sensitive microspheres(Gel-MS/tanshinone IIA) has been designed and synthesized in this study. The thermosensitive hydrogel exhibits good mechanical properties after reaching body temperature. Microspheres initially immobilized by the gel exhibit excellent reactive oxygen speciestriggered release properties in a high-reactive oxygen species environment after myocardial infarction onset. As a result, encapsulated tanshinone IIA is effectively released into the infarcted myocardium, where it exerts local antipyroptotic and anti-inflammatory effects. Importantly, the combined advantages of this technique contribute to the mitigation of left ventricular remodeling and the restoration of cardiac function following tanshinone ***, this novel, precision-guided intra-tissue therapeutic system allows for customized local release of tanshinone IIA, presenting a promising alternative treatment strategy aimed at inducing beneficial ventricular remodeling in the post-infarct heart.
